Abstract
Background: Epilepsy, characterized by recurrent, unprovoked seizures due to anomalous brain activity, is a significant complication for patients with intracerebral hemorrhage (ICH). The onset of epileptic convulsions during the acute phase of ICH can worsen the patient's prognosis and survival chances, making it crucial to identify a safe and effective method to prevent these seizures. Levetiracetam, a pyrrolidone derivative, is noted for its unique mechanism of action, exceptional tolerability, and advantageous pharmacokinetics, making it efficacious against various types of seizures. Objective: This study aims to evaluate the safety and efficacy of levetiracetam in preventing epileptic seizures during the acute phase of ICH and to determine its impact on neurological outcomes in this patient population. Methods: A cross-sectional investigation was conducted between October 2022 and June 2023 at Pak Emirates Military Hospital in Rawalpindi, Pakistan, involving 85 patients with spontaneous ICH confirmed by CT or MRI within 24 hours of symptom onset. Inclusion criteria included adult patients aged 18 or older, with various forms of ICH, excluding isolated subarachnoid hemorrhage, penetrating wound injury, depressed skull fracture, or early posttraumatic seizure. Patients with a Glasgow Coma Scale (GCS) score of less than 6, serum creatinine level >1.7 mg/dL, history of psychosis, unprovoked seizures, cerebrovascular accidents, traumatic brain injuries, or encephalitis within the previous three years were excluded. Patients were administered an initial loading dose of levetiracetam (1,000 to 1,500 mg), followed by a maintenance dose (500 to 1,500 mg every 12 hours) based on renal function. Continuous electroencephalography (cEEG) monitoring was used to detect seizures for at least the first 72 hours of hospital admission. The primary outcome was the incidence of epileptic seizures during hospitalization, while the secondary outcome was the patient's neurological status at discharge, assessed using the Modified Rankin Scale (mRS). Data were analyzed using descriptive statistics and the Chi-square test, with a p-value of ≤0.05 considered statistically significant. Analyses were conducted using SPSS version 25. Results: The mean age of the patients was 47.89 years (SD=7.46), with 62.35% male and 37.65% female. The mean GCS score at admission was 10.52 (SD=2.13), and the mean volume of ICH was 17.5 ml (SD=3.4). At baseline, 2.35% of patients had GCS scores of 3-5, which improved to 0% after treatment. The percentage of patients with GCS scores of 13-15 increased from 65.88% to 83.52% (p=0.3730). Seizures within the first 7 days occurred in 10.58% of patients, and the overall seizure incidence during hospitalization was 20%. At discharge, 9.41% of patients had an mRS score of 0, and the percentage of patients with an mRS score of 2 increased significantly from 18.18% to 37.64% (p=0.4086*). The percentage of patients with severe disability (mRS score of 5) significantly decreased from 22.72% to 5.68% (p=0.0094*). Conclusion: Levetiracetam is effective in improving neurological outcomes and reducing the incidence of seizures in patients with acute intracerebral hemorrhage, with a manageable safety profile. These findings suggest that levetiracetam can be a valuable addition to therapeutic strategies for managing ICH-related seizures, potentially enhancing patient care and improving health outcomes.
